A boy is walking over a railroad bridge at three miles per hour. He is two fifths of the way across when he hears the whistle of an approaching train. "Oh no, what shall I do?" he cried.
A frog who had been wedged between the slats for the last two days answered: "Run back the way you came! You will get off the bridge faster that way!"
The boy turned, but as he did so, a fish popped its head out of the river below them. "No!" it said. "Run away from the train! It will take longer for the train to reach the far end of the bridge than the near end!"
"That's ludicrous!" Shouted the frog.
Before they could continue, there was a rumble and a thud, and the fish and frog averted their eyes.
